Answer:
45.2pi inches
Step-by-step explanation:
C=2×pi×r
since the answers already have pi we don't need to multiply it
C=2×22.6 = 45.2pi inches
Answer:
A. 22.6π
Step-by-step explanation:
Given:
22.6 inches across = diameter
What we need to find is how much ribbon do we need, so we use the formula:
C = 2πr
C = Circumference
r = radius = half diameter
Since we know the diameter, we do half of it to get the radius
22.6 ÷ 2 = 11.3
radius = 11
Now we substitute this into the formula:
C = 2πr
Substitute radius into formula
C = 2π(11.3)
Multiply 2 and 11.3
C = 22.6π

A meat-seller sells x kg of ducks at $8.50 per kg and (2x + 5 ) kg of chicken at $3.60 per kg. If he collects a total of $206.40, find the value of x.
Answer:
[tex]x = 12[/tex]
Step-by-step explanation:
1) Set up an equation that involves all of the values; the price and kg of each duck and chicken equating to 206.40.
[tex]8.50(x) + 3.60(2x + 5) = 206.40[/tex]
[tex]8.50x + 7.2x + 18 = 206.40[/tex]
2) Solve it.
[tex]15.7x + 18 = 206.40[/tex]
[tex]15.7x = 206.40 - 18[/tex]
[tex]15.7x = 188.4[/tex]
[tex]x = \frac{188.4}{15.7}[/tex]
[tex]x = 12[/tex]

Step-by-step explanation:
Two numbers whose sum is 29 and their difference is 15
Answer:
22 and 7
Step-by-step explanation:
Let x and y be the two numbers we are looking for:
The statement “their sum is 29” means x + y = 29
The statement “their difference is 15” means x - y = 15
we get this system:
x + y = 29 (1)
x - y = 15 (2)
Let’s solve it :
(1) + (2) ⇒ x + y + x - y = 29 + 15 ⇒ 2x = 44 ⇒ x = 44/2 = 22
Now we replace x by 22 in equation (1) :
22 + y = 29 ⇒ y = 29 - 22 = 7

Which of these graphs represents a function
Answer: Answer X
Step-by-step explanation:
In order for a graph to represent a function, it must pass the vertical line test. This means, if you were to draw a vertical line at ANY point along the graph, it should not intersect more than one point. For answers W, Y, and Z, they clearly fail the vertical line test. Answer X is the only graph that passes the vertical line test.

Can someone help me with this problem?
Explanation:
22 = 2*11
18 = 2*9
We see that 2 is the GCF of 22 and 18. It's the largest shared factor.
Now use the distributive property to say the following
22 + 18
2*11 + 2*9
2(11+9)
To check the answer, multiply the outer 2 by each term inside to end up with 22+18 again.

Latonya was just hired as an engineer for an electric company. she will make a salary of $50,000 a year. how much of latonya's salary will be taxed at the 10 percent rate? how much of latonya's salary will be taxed at the 28 percent rate?
The $5000 will be taxable amount at 10% of Latonya's salary, and $14000 will be taxable amount at 28% of Latonya's salary.
What is the income tax rate?It is defined as the tax rate applied on the solely earned money by a single entity.
Latonya salary per year = $50,000
If Latonya's salary will be taxed at the 10% rate, then she needs to pay tax:
[tex]= $50,000\times10\%[/tex]
[tex]=50000\times \frac{10}{100}[/tex]
[tex]= \$ 5000[/tex]
If Latonya's salary will be taxed at the 28% rate, then she needs to pay tax:
[tex]= \$50,000\times28\%[/tex]
[tex]=50000\times \frac{28}{100}[/tex]
[tex]= \$14000[/tex]
Thus, the $5000 will be taxable amount at 10% of Latonya's salary, and $14000 will be taxable amount at 28% of Latonya's salary.

which is an equation of the axis of symmetry of the graph of the equation y= x^2-6x+2?
1) x=-3
2) y=-3
3) x=3
4) y=3
Answer:
x=3
Step-by-step explanation:
The equation is written in the form ax2+bx+c. As you can see, a=1, b=-6 and c=2. The axis of symmetry is worked out by x=−b2a.
−(−6)2(1) = 62=3
Substituted this value of x back into the equation to find the y coordinate.
y=(3)2−6(3)+2
y=9−18+2
y=−7q
So the vertex of the line is at (3,-7)

[tex]5 \sqrt{6} [/tex]
[ yes ] [ no ]
15 [ yes ] [ no ]
[tex] \binom{\pi}{4} [/tex]
[ yes ] [ no ]
The expression a/b * c/d is an illustration of number types
The truth value of 8.96 is yesThe truth value of 5√6 is noThe truth value of 15 is yesThe truth value of π/4 is yesHow to determine the true values of the numbers?The expression is given as:
a/b * c/d
Next, we test the given numbers
(a) 8.96
Express 8.96 as a fraction
8.96 = 896/100
Express the numerator and the denominator as products
8.96 = (224 * 4)/(50* 2)
Split the fraction
8.96 = 224/50 * 4/2
The above equation shows that 8.96 can be written in the form a/b * c/d.
Hence, the truth value of 8.96 is yes
(b) 5√6
Express 5√6 as a product expression
5√6 = 5 * √6
Evaluate the product
5√6 = 12.2474.....
The result of 5√6 is a non-terminating decimal
Hence, the truth value of 5√6 is no
(c) 15
Express 15 as a fraction
15 = 90/6
Express the numerator and the denominator as products
15 = (9 * 10)/(3 * 2)
Split the fraction
15 = 9/3 * 10/2
The above equation shows that 15 can be written in the form a/b * c/d.
Hence, the truth value of 15 is yes
(d) π/4
Express π as 22/7
π/4 = 22/7/4
Rewrite the expression as products
π/4 = 22/7 * 1/4
The above equation shows that π/4 can be written in the form a/b * c/d.
Hence, the truth value of π/4 is yes

Q.1. The potter at a pottery store makes two sizes of vases. The larger size takes six hours to make, and the smaller size takes 1.5 hours to make. The potter works 30 hours a week. She needs to make at least six total vases a week, including at least two of each size. Give one example of how many of each type of vase the potter can make.
Answer:
Step-by-step explanation:
Let x and y be the large (x) and small (y) vases the potter makes in one week.
We are told that the large and small vases require 6 hours for each large(x) and 1.5 hours for each small (y) vase. The combination of large and small vases made in one week thus requires a total time of:
6x + 1.5y = total hours/week
We are told that the potter works 30 hours per week, so:
6x + 1.5y = 30 hours
We also learn that she needs to make at least 6 vases in a week, so:
x + y => 6
Plot the two equations:
6x + 1.5y = 30, and
x + y => 6
This will produce the attached grap, Vases1. The inequality appears as the shaded area in the upper area. Any point in the shaded area satisfies the inequality of x + y => 6. The x and y intercepts are at (0,6) and (6,0), representing either all large (x) or small vases (y).
The lines intersect at (4.67,1.33). This represents a fictional combination of 4.67 large and 1.33 small vases. This results in 6 vases (4.67 + 1.33) that require a total of 30 hours to make (6*4.67 + 1.5*1.33) = 30 hours. If you want to select whole number answers, they appear at (0,6), (2,4), (4,2), and (6,0). (x,y or large,small). All combinations result in 6 vases, but eould require less than the 30 hours of time available. Any whole number combination in the area below the line 6x + 1.5y = 30, but above the line x+y =>6 are valid, such as (4,4). This area is shown in Vases2. The valid area for making choices has the darkest shade, where the two inequalities are both satisfied.

A. 11
B. 10
C. 60
D. 48
E. 15
ty!
If all of their dresses are fit for the kids, the possible way to dress them is 3*4*5=60
But one dress is out grown for the third child. Hence, the combination that are not possible.
3*4*1=12
So total number of possible ways are :
3*4*5 - 3*4*1=48
Hence the answer is option D.
